I want to increase the priority of the new 'Re-Crawl Index Documents' feature implemented at the bottom of the page 'IndexReIndexMonitor_p.html'. I love this feature and I want to give this thread a higher priority since no other crawls are currently running on my main peer.

Thank you very much. I just applied custom values at this page and saved the new values. But shortly after that the values got reset to their default values. I'm looking for something in the java code to change the thread priority. At that time we migrated the build-in index to Solr we had a procedure to migrate the old index to Solr. This procedure ran at low priority in the background. I just changed a value of a variable in the java code to take influence of the thread priority and then it ran much faster. Is this also possible in context I described above? If so, in which class should I made the change and whats the exact area of the corresponding code?

Hi LA_FORGE,you are right, the log traces you mention are from the postprocessing task.More precisely, the related code from version 1.92 is in the CollectionConfiguration.createRankingMap() private function called by the postprocessing one : see the first trace and the next.
